APPARATUS FOR DYEING, 800.

SPECIFICATION forming part of Letters Patent No. 323,819, dated August4-, 1885.

Application filed March 27, 1885. (No model.)

To all w/wm it may concern:

Be it known that 1, WILLIAM llIATI-IER, a citizen of England, residingat Salford, in the county of Lancaster, England, have invented apparatusfor soaking, boiling, or dyeing textile materials or subjecting them tothe action of liquids or gases, (for which I have made application forLetters Patent in Great Britain, dated th March, 1885, No. 3,096,) ofwhich the following is a specification.

The soaking and boiling of textile materials for cleansing, bleaching,and dyeing operations are usually effected in kiers or vessels in whichthe material is piled in mass and sub- 1 jected to the action of liquor,boiling liquor and steam. Owing to the difficulty of penetrating themass, the process must be continued for a long time, and the action isby no means uniform over the whole of the material. Moreover, a longtime is occupied in charging the kier before the action can becommenced, and afterboiling has terminated the kier is cooled down inthe operation of emptying it, which also occupies a long time andinvolves great waste of heat.

My invention relates to means of avoiding the disadvantages attendingthe present system of heating the material by the use of apparatuswhereby I am enabled to abridge the time and to economize the labor andheat re quired, and at the same time to secure great uniformity oftreatment throughout the whole of the material operated on.

Figure 1 of the accompanying drawings is a longitudinal section, partlyin elevation, and Fig. 2 is atransverse section, of apparatus accordingto my invention, which, by way of illustration, I will describe asapplied for boiling.

A is a cylindrical vessel, like aboiler, placed with its axishorizontal. It is made with a double shell, forming round it an annularsteam-jacket, B. At each end it is fitted with a vertically-slidingdoor, 0, arranged like a wedge sluice-valve, which, when pressed downits inclined guides, tightly closes the end of the vessel. In the lowerpart of the vessel are fixed rails R, on which run open-framed orlattice trucks T, which are made of shape approximately correspondingwith the interior of the vessel A, but smaller, so as to leave space allround them within A. The metal of these Patented in England March 10,1885, No. 3,096.

trucks should be enameled, or otherwise coated, so as to prevent soilingof the material which they contain. In the lower part of the vessel, atthe sides and ends, are fixed partitions P, nearly fitting to fillets onthe trucks T, so" that, when the trucks are in position, these act asstops, preventing free flow of liquor around them.

. S is a steam-boiling pipe, perforated with numerous holes andextending along the bottom of the vessel. L is aliquor-pipe, extendingpartly along the top and terminating in distributing-nozzles N. From thepipe L a branch, L, leads to a supply-cistern, and a branch, L leads tothe discharge of a rotary or other circulating pump. From the bottom ofthe vessel Athere is a pipe, M, which leads by one branch to a drain orother outlet and by another branch to the suction of thecirculating-pump. D is a steam-pipe supplying the jacket 13, andE is apipe for running off water of condensation. The pipes S, L, D, and E,and their branches are supplied with suitable cocks or valves.

F and G are pipes leading to safety-valves for the jacket B and theinterior of A, respectively. At each end, outside thevessel, arecontinuations of the rails R,with suitable bridgepieces 0, that can befolded down when the doors 0 are raised.

Several sets of the trucks T being provided, the operation is carried onin the following manner: A pair of the trucks T, which have been chargedoutside with the material to be operated on, are run on the rails intothe vessel A, and the doors Gare tightly closed. The casing 13 issupplied with steam and a quantity of suitable liquor run into thevessel by the pipe L, enough to cover or partially cover the trucks andtheir contents, is heated and kept hot by the steam in the jacket Bandsteam blown through it from the pipe S. By means of the circulating-pumpthe liquor is kept in circulation, being drawn from the bottom of thevessel by the pump branch of the pipe M,

and discharged by the nozzles N, which distribute the liquor over thematerial in the trucks. As the liquor in circulating from top to bottomfinds no free passage outside the trucks, being impeded by thepartitions 1?, it has to find its way mostly through the mateof thatpair.

rial in the trucks,which is also kept in a bath of the boilingliquor,surrounding it on all sides. \Vhen the boiling has been continuedfor such time as may be required,the liquor is run off by the drainbranch of the pipe M, the doors 0 are raised by a steam, hydraulic, orother crane, the trucks T are run out at one end of the vessel, andanother set of trucks, ready charged, are run into it at the other endto have their contents operated upon, as above described. The trucksthat have been run out of the vessel can be unloaded andloaded againwhile the boiling of the material in the other trucks goes on, and thuslittle time is lost, and there is no material cooling of the vesselduring the eX- change of trucks.

The vessel A,in d of having doors at both ends, may have a door, 0, onlyat one end, the other end being permanently closed, and this closed endmay be steam-j acketed. The trucks in that case would be withdrawn andintroduced at the one end only.

Ihave shown in the drawings a pair of trucks in use and a boiling-vesselsuited for reception It is, however, to be understood that the numberand dimensions of the trucks may be varied, and the boiling-vessel maybe made to accommodate only one truck or a number greater than two.

When the apparatus is used for boiling woven fabrics, these may becharged in rope form into the trucks. It is, however, in many casespreferable to treat fabrics spread out to their full width, which cannotbe conveniently done in ordinary kiers. In trucks, such as I havedescribed, fabrics can readily be laid to expose their full width,either folded or wound on rollers.

Obviously, for soaking or dyeing, the same apparatus is applicable.\Vhen the material is to be soaked in cold liquor, the heating by steamis dispensed with. \Vhen the material is to be dyed or acted onchemically by liquids, the dye or liquid is run in, and should itrequire to be heated, this may be doneby admitting steam to the casing Bor blowing steam through the liquid, or both; also, when the material isto be exposed to the action of gasessuch as sulphurous acid, chlorine,carbonic acid,and othersthese gases may be introduced by the steam orthe liquor pipes, or may be made to circulate through the vessel byadmitting them by the one pipe and allowing them to pass out by theother.

For processes not requiring heat, the vessel A may be made without asteam-easing, B.

I am aware that boiler-tanks have been provided with trucks for use invarious arts; and such, therefore, I do not broadly claim.

Having thus described the nature of my invention, and the best means Iknow for carrying the same into practical effect, I claim- 1. Thecombination of the vessel A, provided withatrack, It, alattice oropen-framed truck, T, to run over said track, and a sliding wedgeshapedsluice'valve door, 0, to close the opening at the end of the vessel,substantially described.

2. The combination of the vessel A, provided with a track, It, a truck,T, to run over said track, and a partition, P, in the lower part of thevessel about the truck, substantially as described.

8. The combination, with the vessel A, of the lattice or open-framedtruck T within the vessel, the partitions P in the lower part of thevessel about the truck, and pipes L, provided with nozzles N, and theexit-pipe M for maintaining a circulation of liquid through the vessel,substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, this 10th day of March, A. D1885.

\VILLIAM MATIIEIR.
